7 claims. ,(ci. css- 263) Wringers and the like are Commonly providedwith some form of safety device making the indrawing action of the rollsunder pressure inoperative in case of accident. Suchy safety devices, ofcourse, must be quick acting in order to avoid very serious injury andshould be so easily operated as to be effective under panic conditions.l

The present invention is designed to improve the manner of operating thesafety device in order that the elort to effect` a safety action may bedelivered in a variety of directions and thus add to the certainty ofeffective operations' villustrated in the accompanying drawing asfollows:

Fig. 1 shows a front elevation of a wringer,

partly in section.

Fig. 2 an end elevation of a wringer. l Fig'. 3 a section on the linev,3-3* in Fig. 2." Fig. 4 a` section on the lined-4 in Fig. 3. f Fig. 5a section on the line 5-5 in Fig. 3. The wringer frame, as shown, has abase I, side stiles 2 and 2a, vand a top member 3. Rolls i and 5 aremounted in the frame, these rolls having shafts 6 and 1 respectively,the shaft 6 forming the driving means for the lower roll, the upper rollbeing driven from the lowerroll. The shaft 6 is journaled in bearings 8arranged in the side stiles and resting on the base. The shaft .1 hasbearings 9` slidingly mounted in the stiles. A spring I0 operates on thebearings 9.

The pressure oi the spring is adjusted by aA screw II arranged on thetop member 3.

An interlocking connection is provided at I2 between the top member andthe lower member in a well known manner providing means for detachablysecuring this end of the top member vto the lower part of the frame. Aresetting lever I3 is hinged at |4`at the opposite end of the wringer.The resetting lever is connected by a link I5 with the frame, completinga toggle connection. One end of the link is connected to the lever I3 bya pivot IE. The opposite end of the link is connected by a rod I'l witha channel plate I8. 'Ihe channel plate is secured to the face of one ofthe Stiles. The link I5 is ,U- shaped having two flanges, one at eachside of the channel.

A trip rod I9 extends fore and aft through a cam opening 20iin. thechannel piece I3 and through a cam opening 2| in the side walls of thelever I3, the lever I3 being of channel form. Handles 22 are mounted ateach end of the rod, these handles having cam surfaces 23 which areadapted to engage the corners of the stile. The rod I9 also has a bend25 which may be thrown out of the plane of the 'connecting web of thechannel plate I8 by a rotative movement of the trip rod.

The pivots of the lever I3 are slightlyk out of line, making thevsetting of the lever slightly stable. When itis desired to release thepres- -sure on the rolls, the rod 9 'may be operated `This isaccomplished asr follows:

If the handle 22 is moved up or down, the rod I9 operating on the vcams20 and 2| push the rod outwardly, and rasyit is always against the edgeof the cam 2|, this moves the lever outwardly intov unstable positionand effects a release.

Should the handle 22 be moved outwardly, that is, away from the wringer,the opposite end of the rod would operate as a fulcrum and the rod,operating against the cam surface of the slot 2l! would operate on thecam 2| and move the lever outwardly and effect a release.

Should the handle be moved toward the wringer, the rod fulcrumed in thebottom of the slot 20 would move the opposite end of the rod outwardlyand effect a release. If the rod is moved inwardly, the came surfaces 23arranged on the handle 22 engaged by the operator, operate on thecorners of the stile and move, through the pressure of the rod I9 withthe cam notch 2 I, the lever outwardly and effecta release.

On the other hand, if the handle is pulled toward the operator, the`camming action of the opposite handle will force the rod outwardly andeffect a release.

Again, if the rod is rotated in either direction, the deflections orbends 25 will engage the channel piece I8 and will throw the rodoutwardly carrying with it the lever through engagement with the edge ofthe cam slot 2|, one deection of the bend 25 .being effective for thispurpose when the handle kis turned in one direction and the otherdeflection of the bend when the handle is turned in the oppositedirection.

It will be seen, therefore, that this device i operative throughuniversal action, that is, it may be moved in any direction, push orpull, up

\ rendering wringing action of the rolls ineffective, comprising anoperating member constructed and arranged to act in response to pressurein any and all directions making jsaid safety means effective.

2. In a wringer or the like having a frame' comprising top and bottommembers, rolls mounted in the frame, and a pressure means exertingpressure from the top member on the rolls comprising a toggle connectionbetween the top member and bottom member, the combination with thepressure means of a safety means comprising a trip rod operating on thetoggle to release the pressure on the rolls, said trip rod beingresponsive to pressure on fthe rod from front to rear andsidewiserelatively to the front and rear direction of movement of the rod and*constructed and arranged to act on'the toggle to eiect a release throughbreaking of the toggle.r

S. In a wringer` or the like having a frame comprising top and bottommembers, rolls mounted in the frame, and a rpressure means exertingpressure from the top `member comprising a toggle connection between.the top member and bottom member, the `combination with the pressuremeans of i. a safety means comprising a trip rod operating on the toggleto release the pressureon the rolls, said trip rod being constructed andarranged to be responsive to pressure on the rod from front to rear androtatively about the yaxis of the rod to effect a releasethrough'breaking of the toggle.

4. In a wringer or the like .having a frame comprising top and .bottommembers, rolls mounted in the frame, and a pressure means exertingpressure from the top memberon the rolls comprising a toggle connectionbetween the top member and bottom member, the pivots of the toggle beingarranged to form a stable set position of the toggle, the combinationwith said toggle connection of a rod extending from front to rear andhaving camming engagement in rela` tion to the frame and toggle toactuate the toggle to release position by an endwise movement andfulcrumming on the frame to move the connection to release position by amovement of the rod laterally relatively to the direction of forward andback movement of the rod, the rod having laterally extending partseffecting a movement of the connection to release position by rotative'movement of the rod.

5. In a wringer or the like having a frame, rolls mounted in the frame,and pressure means 4for the rolls, the combination with said pressuremeans of a safety means rendering wringing aotion of the rollsineffective comprising an operating member constructed and arranged toact in'response to pressure in any and all directions for releasing thepressure means.

6. In a wringer or the like having a frame, rolls mounted in the frame,pressure and driving means for the rolls, the combination with saidmeans rendering wringing action of the rolls ineffective ofy a safetymeans comprising a member mounted to rotate about an axis of rotationextending from front to rear of the wringer and to move with said axislaterally of said axis and constructed and arranged to respond throughsaid movements in making said safety means effective.

'7. In a wringer or the like having a frame, rolls mounted in the frame,pressure and driving means for the rolls, the combination with thepressure and driving means of a safety means rendering wringing actionof the rolls ineffective, comprising a trip rod extending in a directionfrom front to rear of the Wringer frame, said rod being mounted torotate about an axis extending from front to rear of the wringer and tomove with said axis laterally of said axis and constructed and arrangedto respond through said movements in making the safety means effective,
